Specification of Letters Patent.

Application filed January 11, 1921. SerialNo. 436,439.

T 0 all whom it may concern:

Be it known that I, Lnwrs Pnnorrr, a citizen of the United States, and a resident of Newark, county of Essex, and State of New Jersey, have invented certain new and useful Improvements in Presses, of which the following is a specification.

This invention relates to a press, and is that type of press that is used for extracting juices from fruits or vegetables, and is constructed so that itis easily operated.

The invention relates to a press of this type in which the basket that holds the material can be easily swung to and from its position in which it is subjected to the pressure means of the press, so that it is not necessary to'bodily lift the basket either to fill it onto empty it.

The invention is also designed to provide a press of this kind which is compact, .requiring but a minimum of head room, and which can be-easilyztaken apart for the purpose of cleaning it.

The invention is illustrated in the accompanyingdrawings, in which Figure l is a side view of oneform of my improved press, and Figure 2 is a central vertical section thereof. Figure 3 is a top View of the press shown in ,Figure 1, and Figure 4 is a section showing'thebase of the support for the press in elevation, part thereof being broken away to show the interior construction. Figure5 is a sectional detail "of a ratchet mechanism for actuating the screw ofthe press; Figure 6 is a perspective View of one of the handles of the ratchet shown in Figure 5. Figure 7 is a detail section showing part of the base and part of one of the baskets and indicating the path that the juices which have been extracted take in passingirom the press. Figure 8 is a detail section on line 8-8 in Figure at, and Figure 9 is a detail view showing one manner of attachingthe basket support sothat the proper location of the basket in relation to the pressure means is assured. Y i I The invention comprises a main support which is preferably cast and consists of a a'top part which in- :Which can be dupli- (rated, as at 12, to form a support for the head 13 in which the pressure means is mounted, the pressure means in the form shown consisting ofa screw 14 working in the nut or screw-threaded bearing 16 in the top of the head 13 and being swivelled to the piston 17 and being operable by the ratchet device 18 which is provided with a removable handle 19. i

The "ratchet mechanism has a body portion 20 in which the handle 19 is seated, as

shown in Figure 5, this body portion 20 bemg made short enough so that it can pass between the standards 11 and 12 and be com- -pletely rotated in the initial operation of the screw 14: so as-to save time, but when leverage is required at the'final stages of the pressing, the handle 19 is inserted, and for the purpose of its reciprocation I provide a ratchet mechanism "which is shown in'detail in Figure 5 and consists of a pivoted pawl 21 which has teeth on itstwo ends, these teeth alternately engaging the teeth 22 of 't he ra'tchet 23.

- On each side of the pawl 21 and in rear of .its two ends are the fingers 24, each of which is actuated by a spring 25 and each of which has a handleportion 26 projecting therefrom, and the operation of rotation of the ratchet can be controlled according to *WlliCllOftllB fingers24 is retracted and-made inoperative, permitting the other to have a spring .action. v Such retraction is possible is to be inoperative and catching the handle '26 in a lateral projection 27 one of these slots 28'being provided'on'each side of the body portion. This, it will be evident, permits the ratchet to be reversed.

-On one of the standards, preferably the standard =11, isarranged abracket 29 which is rotatably arranged on the standard and is provided with means for holdinga. basket trier,

by pushing back whichever of the fingers 24;

of the slot 28,

30. This basket '30iis open-ended, that is,"

the top and the bottom are open, and the sides are made so thatthe juices can escape.

The usual form is by making the body portion of the basket of wooden slats 31 which are separated slightly and which are surroundedby bands 32, and between-the'bands and the slats is arranged the screening 33. "The bracket 29has projecting ears 34 and 'the bands' 32 each have "a; lip 35, which lips are inserted in recesses-in the ears, and then the pins '36 are passed down througha perforation in these elements so as to hold the baskets in place, so that when the bracket 29 is rotated thebasket is carried with it.

The bracket is usually provided with two opposed means, as abovedescribed, for holding the duplicate baskets, so that when one is in a position which places it in line with the pressure means, the other is in position for filling. To permit such filling a temporary bottom is provided in the form of a plate 37 which swings by means of its hub 38 and which can be swung under the basket that is to be filled, indicated at a in Figure 3, and the contents are thus held up, and while the material in the basket under the pressure means is being compressed, the exposed basket is thus filled. When the basket at a is to be swung into position, the bottom which is in the form of a plate, swings with it until it engages the edge 39 of the shallow part it) of the shelf &1, the shelf 41 being approximately arcuate, and the material is thus suspended while this newly filled basket is being swung toward its position under the pressure means. Of course the false bottom 87 stops when it engages the shoulder and forms a substantially flat surface in conjunction with the top surface of the shelf -11, since the top of the shelf and the top of the plate 37 are even, as will be seen from Figure 1.

hen the baskets and their bracket have been swung on the standard 11 until the basket with the material that has been com- 1 ressed is in the position shown at b in Fig- 1"6 4, the caked or compressed material that s in the basket at 7) can be dropped, since there is nothing underneath the basket, and the bottom thus being open, pressure by any suitable instrument, such as a stick, serves to dislodge the material and it drops through. The travel of the baskets is then resumed and the newly filled basket is under the pressure means and the recently emptied basket is ready to be filled as soon as the false bottom 3? is again swung out to the position underenath this exposed or idle basket.

To insure the alignment of a basket under the pressure means I prefer to automatically halt the basket in such position, one such means being shown in detail in Figure 9, in which the latch pin 12, with the handle 13 for its manipulation, is normally projected by a spring 45: so that its end enters either of the recesses 45 in the standard 11, these parts being so disposed that when the latch is in a recess one of the baskets is in position under the pressure means.

The base is provided with a recessed or depressed part 16 which forms a chamber 47 which has a lid 48 on the top, this lid preferably having a central opening 49 so that the juices may pass down through, the base having an annular groove 50 just outside of the basket so that juices squeezed through the screen 33 pass into this groove and through any desired number of passa es 51 to the upper part of the chamber 1%, as will be seen from Figure 7, the chamber at having an outlet tube 52 at the bottom. A screen is installed so that it is beneath the passages 51 and is usually mounted on a frame 54: which has legs 55 which hold it above the bottom of the chamber 17.

The plate 37 which forms a temporary bottom for the basket that is being filled is also provided with an annular groove 56 which has an opening 57, so that any drippings from the material being placed in the basket or which rests for a time in the basket, run into the groove 56, the lowest point of which is provided with the opening 57 which is arranged near a curved groove or pasasge 58 which leads to one of the openings 51, as will be seen from Figure 4:, whereby this material is also deposited on the screen 53 in the chamber 47 and passes out with the material from the other basket through the outlet 52 into a suitable receptacle on the outside of the press.

It will be seen that one or more baskets can be used in this press, and when a basket which has been filled in the exposed position at a in Figure 3 is desired to be swung around to its position under the pressure means, it necessitates only sufficient raising of the piston 17 of the pressure means to permit the basket to be passed under it. ihis eliminates any excessive raising of the pressure means and permits a compact press, since the head 13 is comparatively low.

The operation of the press is rapid, since there is no unusual delay in filling or emptying the baskets, since, as above described. material can be dropped from the basket when it is swung from under the pressure means to the position shown at b in Figure 1, and after it is emptied it can be at once placed in the position shown at a in Figure 3, where it is filled. While this filling is taking place the other basket, which is now under the pressure means, is having its contents subjected to the action of the pressure means, so that the filling of one basket and the compressing of the material in the other can take place at the same time.

It will be understood that minor changes may be made in the details of construction without departing from my invention.

I claim:

1. A press comprising a support, a pressure means on the support, the base of the support being recessed and having an annular groove around the mouth of the recess, the base having passages from the groove to the upper part of the recess, a cover on the recess, and a screen mounted in the recess below the passages.
